MANlFOLDlNG-PEN.

SPECIFICATION forming part of Letters Patent No. 473,20*?, dated April19, 1892. Application filed September 2l, 1891. Serial No. 406,351. (Nomodel.)

To @ZZ whom t may concern:

Be it known that I, AUGUSTUS C. CAREY, a citizen of the United States,residing at Lake Pleasant, in the county of Franklin and State ofMassachusetts, have invented a certain new and nsefulImprovementinManifolding-Iens, of which the following is a full, clear, and eX- actdescription.

The object of thisinvention is to provide an efficient pen for producinga number of written copies simultaneously by driving the ink through aseries of superposed sheets of paper or writing material. Manifolding inthis way has been publishedby meheretofore, an dhence the presentinvention relates only to the writing or manifolding instrument.

I will describe the principle of nry invention first and the best modein which I have contemplated applying that principle, and then willparticularly point out and distinctly claim the part or improvementwhichI claim as my invention.

In the accompanying drawings, illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure l is a sideelevation, and Fig. 2 a plan View, on one scale. Fig. 3 is alongitudinal section on a larger scale, with the fountain and stylusbroken out midway, so as to bring the figure within the sight. Fig. 4 isa cross-section of the driving-head, and Fig. 5 shows in elevation andplan the end of the tube which surrounds the stylus.

The fountain or barrel a, is provided with a point or nib b, the twobeing united by a screwthread or other joint.

c is an ordinary cap for the point.

d is the stylus.

c is a tube within the fountain or barrel- The point of this tube ismade with an enlargement f, which co-operates with the bore g of thepoint or nib b to center the stylus with relation to said point or nib.This enlargement f is grooved longitudinally, as clearly shown in Fig. 5at f', to permit the outiiow of writingiiuid. The tube e is made with orfixed toa head h, having a screw-thread by which the washers j areinterposed to make a tight joint. The barrel,if made of usual frangiblematerial, such as gutta-percha, may have its upper end reinforced by aband of metal Zt, thus making its joint with the head h more secure. Thehead h is provided with a screw-threaded neck Z, which is constructedwith a circumferential groove m, in which lits a bindingscrew fn., andthis screwis tapped into the screwthreaded shank o of the driving-head.The stylus c extendsthrough the head 71 and the upper end of this stylusis made as or with a tappet p, between which and the neckl a retractingspring q is arranged. This tappet is engaged by a cam r, having one ormore cam-surfaces, to give tothe stylus a rapid longitudinal motion. Thecam r is arranged 'upon a sleeve or hollow shaft s, and this shaft ismounted and revolves upon a screw-bolt t, which is supported upon thecheeks u of the driving-head. Upon the shaft s are the pulleys o toreceive bands for driving the cam.

-It will be understood that the pen is designed to be powerdriven, andany suitable motor may be employed; but whatever the source of power Iprefer to use two drivingbands, because thereby the pen is more evenlybalanced and rendered easier of manipulation and guidance than where asingle band is used; but I do not mean to exclude a single driving-bandfor the pen, as quite obviously it may be used. The cheeks u may be tiedtogether by rods 1U.

The stylus is provided with an arm for use in moving it independently ofthe spring and cam to clear out dirt or sediment from the point. Thehead h is pierced transversely by a canal fy, which intersects thestylus way therein. One end of this canal is continued as a tube z,which ends in an enlargement 2, to which is secured an ordinary air-bulb3. rIhe other end of the canal y is screw-threaded to receive a screw 4,the point of which is adapted to close the canal. The screw 4 is madewith a longitudinal groove 5, which opens communication between theexternal air and the canal y. A canal 6 leads from the canal y into thefountain or barrel c, and a canal 7 serves to connect the bulbs canalwith the said fountain or barrel. Because IOO the serer t controls theair-passages I call it herein the air-screw. The rods w also subservethe purpose of preventing the drivingbands from jumping or slipping offthe pulleys.

The operation is as follows: To supply the fountain or barrel withWriting-fluid, the airscrew 4: is turned to close the canals, the pointb is removed, and the pen turned upside down,

the bulb is compressed, the fluid poured in,A

them and so eifectually clear them. The bind-,

ing-screw n is loose'ned and the neck Zrotated in the shank o one way Orthe other, in order to increase or decrease the length of projec-f tionof the stylus beyond the nib to provide for penetrating a greater Orless number of sheets--that is, to say, for making many or few copies atone writing. By the centering of the enlargement f in the point, thestylus is not only kept centered with relation to the point, but thesaid stylus is kept surrounded with ink.

Bythe construction of pen herein described the work of manifoldingwritings by flowing the ink through a number of superposed sheets ofpaper may be very quickly and effieiently done. It will be understoodthat the original and all copies are made at one and the saineoperation.

I have thus described what I believe to be the best mode of applying theprinciple of my invention; but I wish to be understood as not limitingmyself to the exact details of con` struction7 excepting as such mayform the subject of specific ciai ms. Moreover, por

tions of myinvention may be applied to stylographic pens and otherfountain-pens.

That I claim is l. A pen comprising a reciprocating stylus extendingthroughout the pen and projecting :from both ends thereof, and means toimpart the reciprocating movements to such stylus, a surrounding tubeterminating in an enlargement, a fountain surrounding the tube andstylus, and a point or nib in which the enlargement is located to centerthe stylus in the point, substantially as described.

2. A pen comprising a stylus, a surrounding tube, an ink-fountain, anair-valve coinmunicating with such fountain, and an airforeingapparatus, also connected therewith, substantially as described.

3. A pen comprising a stylus, a tube surrounding it and terminating inan enlargement, a head on such tube terminating in a serew-threadedshank having a circumferential groove, a driving-head having ascrewthreaded shank, into which the screw-threaded neck is iitted, and abindingscrew fitted to said circumferential groove tO permit theadjustment of the neck in the shank to cause the stylus to project moreor less beyond the point, and a fountain having a point in which theenlargement is placed to center the stylus with relation to the point,substantially as described.

4. A driving-head having a cam, a hollow cam-shaft, a driving medium,and a screwn bolt passed through the hollow cam-shaft and constitutingthe axis for said shaft and secured in the drivingdiead, combined with apen-barrel, a stylus, and intermediate connections, substantially asdescribed.

In testimony whereof I have hereunto set my hand this 16th day OtSeptember, A. D. 1891.
